I'm not arguing "merely". I'm arguing necessary. I'm not arguing
sufficient. Arguing "Don't plug the leak in the boat here because there
is another leak over here as well" is rather weak and seems to be the
straw man of the Microsoft coprosperity sphere lately. But I'm in favor of
plugging all of the holes. Let's have an extended conformance class and
an unextended conformance class. Let the market decide which one they
prefer for any particular use. Do you have problems with that?
